Natural Factors 5-HTP (5-Hydroxytryptophan)

Happiness, health, and general well-being are intimately tied to the secretion of various hormones, neurotransmitters, and other chemical messengers. One of these, serotonin, has a powerful determinant over our emotional state, appetite, sleep habits, and pain tolerance. Many prolonged diseases, including depression, have been clinically linked to low serotonin levels.

Serotonin is made in our bodies, but the building blocks it needs are often lacking. Natural Factors 5-HTP provides those necessary building blocks in the form of 5-hydroxytryptophan, a point-blank precursor to serotonin.This formula intensifies sleep quality by improving REM sleep and increases serotonin levels without creating dependence.

Have noticed a calming effect, so far so good

Gave me more stiffness

I have chronic neck pain and severe stiffness. I wanted to lift my mood a little, but this product increased my stiffness within one day. I cannot take it.


Le produit naturel qui m’aide le plus à m’endormir et à augmenter la durée du sommeil.

Pain relief

I have found that taking the 5HTP the soreness I had in my upper arm when I lifted it has gone away and so intend to continue taking this supplement.


I take this along w/ L-Tryptophan and L-Theanine... the combo of these, along w/ a "circadiuan rhythm reset", and I now sleep like a baby after horrible months/years of very little sleep. There aren't enough thanks to go around.
